I bought the standard knife, 3.1. It comes with aluminum tubes with plastic inserts. Green tires front and back, metal screws instead of aluminum,
Like OD said, standard aluminum AE rear motor mount and plastic Left rear bulk head. Everything else is the same as the bloody red version except the color and maybe stock spring for the center shock which doesn't matter cause you NEED the spring kits. I HATE aluminum screws.
